The change in Windows 10 to allow unprivileged creation of links will be supported implicitly in 3.7, but this change is more for convenience than necessity. SeCreateSymbolicLinkPrivilege can be granted to standard users and groups. On my own systems, I grant this privilege to the "Authenticated Users" (S-1-5-11) well-known group. This even allows administrators to create symbolic links without having to elevate.
